I finished "Bones to Ashes" by Kathy Reichs today. It's about a bone expert (Temperance Brennan) who studies bones to see if she can work out how someone died. Reich's books alternate between Montreal and North Carolina (her character's an expert for both cities) and this book is set in Montreal.
The book focuses on two cases. One focuses on some possibly old bones with weird markings on them (Brennan almost convinces herself they might be the bones of a friend who disappeared when she was 14), the other focuses on dead bodies that turn up in a frozen lake. The bones by some miraculous coincidence turn out to be related to her former friend's brother-in-law.
It's the tenuous connections that allow Brennan to be inserted into cases she shouldn't really play and part in that have started to irritate me about Reichs books. Couple this with the fact she has a tendency to stop and have temporary reminders about the plot at regular intervals and I've probably decided that I won't read any more of Reich's books for a while.
